目前,选育谷子杂交种,主要采用测交筛选法,育成一个优良杂交种往往需要测配大量的杂交组合和多年的田间试验,育种周期较长,效率较低。采用预测法,测定一个组合,只用40分钟左右,因而能在较短的时间内测定大量的组合,从中把有杂种优势的组合选拔出来,再进行田间试验,这样就可以大大 At present, the selection of millet hybrids, mainly by screening and screening method, breeding a good hybrids often need to test a large number of hybrid combinations and years of field trials, breeding cycle longer, less efficient. Using the predictive method, a combination is measured in only about 40 minutes, so that a large number of combinations can be measured in a short period of time, from which the combinations with heterosis are selected and further field trials are performed,
